With the development of the mobile Internet, more and more devices are connected to the mobile network, and new services and applications are emerging in an endless stream. The global mobile broadband users are expected to reach 9 billion in 2018. By 2020, the capacity needs of mobile communication networks are expected Increase 1000 times in current network capacity. The skyrocketing mobile data traffic will bring severe challenges to the network. First, according to the current development of mobile communication networks, the capacity cannot support a thousand-fold increase in traffic, and network energy consumption and bit costs are unbearable; second, traffic growth will inevitably bring further demand for spectrum, and mobile communication spectrum is scarce, and the available spectrum is Large-span, fragmented distribution, it is difficult to achieve efficient use of spectrum; in addition, to increase network capacity, network resources must be used intelligently and efficiently, such as intelligent optimization for business and user personality, but the capabilities in this area are insufficient; finally, future networks It must be a heterogeneous mobile network with multiple networks coexisting. To increase network capacity, it is necessary to solve the problems of efficiently managing each network, simplifying interoperability, and enhancing user experience. In order to solve the above-mentioned challenges and meet the increasing demand for mobile traffic, it is urgent to develop a new generation of 5G mobile communication network.

Permanent magnet maglev train has the characteristics of safety and reliability, small operation and maintenance, weather resistance and punctuality, low noise, and low vibration. It is an inevitable choice for the next generation of high-speed ground vehicles. The existing maglev technology can be briefly divided into three types: electromagnetic levitation (normally conductive), superconducting maglev and permanent magnet maglev. Electromagnetic levitation includes Changsha maglev line (China's own technology) and Shanghai maglev line (German technology); superconducting maglev is represented by the Yamanashi line in Japan; permanent magnet maglev has the typical characteristics of "zero power" levitation, but it is difficult to process . In recent years, with the rapid advancement of technologies such as permanent magnet materials, electronic information, and precision machining, permanent magnet levitation technology has once again received extensive attention in the industry.

The permanent magnet maglev train moves fast, has a large carrying capacity, and is in a complex electromagnetic environment. Therefore, when the traditional communication technology is applied to the permanent magnet maglev train, there are problems such as poor signal quality, high communication delay, low data transmission quality, and unstable communication. This not only seriously affects the experience of passengers when riding, but also affects the train. Safe, reliable, and stable operation also poses huge challenges. And 5G technology has the advantages of fast transmission speed, high traffic density, large number of connections, short air delay, high spectrum efficiency, and good mobile performance. But at present, there are few research applications on 5G in the field of rail transit. Therefore, based on the in-depth integration of emerging technologies such as composite sensors, embedded systems, Internet of Things, cloud computing, big data, and artificial intelligence, the new generation of maglev train operation control systems will be studied, and 5G technology will be introduced into the permanent magnet maglev rail transit system. The normal and safe operation of the maglev rail transit system is of great significance to the development of my country's maglev rail transit.
